Gattis placed on 7-day concussion DL

HOUSTON -- As expected, Astros catcher/designated hitter Evan Gattis was placed on the seven-day concussion disabled list Saturday with a mild concussion. It's unclear how long Gattis will be out, and the team called up catcher Juan Centeno from Triple-A Fresno prior to Saturday's game.

Gattis was stunned when he was hit on the side of the head on a backswing by the Rays' Corey Dickerson in the eighth inning Thursday. He stayed in the game and caught in the ninth inning, but he started reporting concussion symptoms to the training staff on Friday.

HOUSTON -- As expected, Astros catcher/designated hitter Evan Gattis was placed on the seven-day concussion disabled list Saturday with a mild concussion. It's unclear how long Gattis will be out, and the team called up catcher Juan Centeno from Triple-A Fresno prior to Saturday's game.

Gattis was stunned when he was hit on the side of the head on a backswing by the Rays' Corey Dickerson in the eighth inning Thursday. He stayed in the game and caught in the ninth inning, but he started reporting concussion symptoms to the training staff on Friday.

"We're hopeful that it might just be the seven days, but at this point we don't know," Astros manager A.J. Hinch said. "This was a very difficult one to assess because he had no concussion symptoms when the play happened. After the game [and when he saw the doctors], he had no concussion symptoms. He woke up the next day and had concussion symptoms. That part's scary."

Astros starting catcher Brian McCann was on the disabled list earlier this year after sustaining a concussion when he took a foul ball off the mask on Mother's Day in New York. Hinch said Gattis' activity level will be monitored while he's on the DL.

"We'll monitor him and go by the doctor's orders," Hinch said. "I think he's going to see another doctor again [Saturday]. It's a day-to-day protocol we have to go through. There's tests to be taken, doctors he needs to see."

Hinch said Springer (quad strain) ran the bases on Saturday and could be activated in time for Tuesday's game against the White Sox in Chicago. Harris (shoulder discomfort) will travel with the team to Chicago to continue his rehab program, though he hasn't started throwing yet.
